I remember getting bit by some bugs/insects a few years ago..Can cause problems, you'll have to get yourself a lot of insect spray and go around your flat with it and get rid of the buggers.

Insects like humidity 40% and above so it's a good idea to keep your flat dry at least less than 40% humidity, you can get humidity/temperature meters on ebay. I showed you one a long time ago, that I bought on ebay for £5.. I remember posting the photo's of it on Simon's forum somewhere http://www.ebay.co.uk/sch/i.html?_trksid=p4684.m570.l1313&_nkw=temperature+humidity+meter&_sacat=0&_from=R40
